Hey,
Just saw this online. Hope this helps!
"How do I tell if there are hardwood floors under my carpet? What do I do if there are hardwood floors down there? The easiest and least intrusive way to see if there are hardwood floors under your carpets is to take out one of your floor registers. The carpet will not be tacked down there. Lift if up and see if the floor underneath it is hardwood, linoleum, or something else. What this can?t tell you is the condition of the floors. If you want your old floors to be restored, you should contact a flooring company with experience in restoration. Sometimes there is water damage, sometimes there are patches, sometimes parts of the floor have been replaced with plywood. A restoration expert can help with lots of these things. But, mentally at least, I would always be prepared to put carpet back down if the floor was too badly damaged."
Sorry I am unsure if you will still need tools to lift even a part of the carpet area that is not tacked down.
